Researchers have developed a method to accelerate AI solvers for the game "The Witness" by automatically learning a predicate. This learned predicate predicts whether a partial path in a puzzle is likely to lead to a solution, enabling the pruning of less promising search states. The approach demonstrated a six-fold speedup in solving puzzles while maintaining completeness and outperforming existing search algorithms and neural network-based competitors. AI
IMPACT This research demonstrates a novel method for improving AI search efficiency, potentially applicable to other complex combinatorial problems.
